Abstract
A method and apparatus for transferring workpieces to successive work devices. The apparatus comprises concentric turntables mounted for rotation about a common central axis. A series of work devices are mounted on the inner turntable and a series of workpiece holder devices are mounted on the outer turntable. The turntables are rotated in the same direction and in synchronism while the various work devices respectively perform work operations on the various workpieces held in the various workpiece holder devices, whereafter the inner turntable is accelerated and the outer turntable is decelerated until the various workpieces reach a position midway between successive work devices, whereafter the inner turntable is decelerated and the outer turntable is accelerated until the workpieces arrive at positions of alignment with the next successive work devices.
